Description
Vibrations-Klassiervorrichtung Zum Trennen verschiedener Korngrößen werden vielfach Siebe verwendet, die aber bezüglich der Korngröße sehr bald eine untere Grenze finden, weil sehr feine Siebe auch sehr dünne Siebwerkstoffe bedingen, die sehr empfindlich sind, zumal wenn es sich um stark schleißendes Material handelt. Bei sehr feinem Material sind Trenneinrichtungen, die nach dem Windsichtverfahren arbeiten, besser. Ein Nachteil ist jedoch, daß die zur Sichtung benutzte Luft mit Staub angereichert wird und daher einem Entstauber zugeführt werden muß. Man trennt also ein Gemisch dadurch, daß man ein anderes Gemisch herstellt, nämlich Staub-Luft. Die Trennung dieses zweiten Gemischs ist dann Aufgabe des Entstaubers. Mit Vergrößerung der Luftmenge zur Sichtung größerer Mengen vergrößert sich daher auch der Entstauber. Es ist auch bereits der Vorschlag gemacht worden, schräg gestellte »Scheideplatten« in eine solche Schwingung zu versetzen, daß grobe Teile entgegen dem Schwingungsantrieb sich abwärts bewegen, während gleichzeitig feine Teile der Richtung des Schwingungsantriebs folgend aufwärts wandern. Diese Apparate haben jedoch keine Verbreitung finden können, zumal der große Einfluß der Oberflächenbeschaffenheit der Scheideplatte noch nicht erkannt war und infolgedessen eine gute Abscheidung eine mehrmalige Hintereinanderschaltung solcher Geräte notwendig machte, wodurch die Apparate kompliziert und teuer wurden.Vibration classifying device For separating different grain sizes Sieves are often used, but with regard to the grain size, they soon become one Find the lower limit, because very fine sieves also require very thin sieve materials, which are very sensitive, especially when the material is very abrasive. In the case of very fine material, there are separating devices that use the wind sifting method work better. A disadvantage, however, is that the air used for the sifting with Dust is accumulated and must therefore be fed to a dust extractor. One separates a mixture by making another mixture, namely dust-air. The separation of this second mixture is then the task of the deduster. With magnification The amount of air used for the sifting through of larger amounts therefore also increases the size of the deduster. The suggestion has already been made to use inclined "cutting plates" to put in such a vibration that coarse parts oppose the vibration drive move downwards while at the same time fine parts of the direction of the vibration drive then hike upwards. However, these devices have not been able to find widespread use. especially since the great influence of the surface quality of the cutting plate is not yet was recognized and, as a result, a good separation was a multiple series connection made such devices necessary, making the apparatus complicated and expensive.
Die Erfindung vermeidet diese Nachteile dieser bekannten Vorrichtungen, indem die zur Klassierung von Materialmischungen vorgesehene schwingende Rinne aus zwei um einen bestimmten Winkel zueinander geneigten Flächen besteht, deren Schnittlinie zur Horizontalen einen weiteren Winkel bildet und die Impulsrichtung des Schwingungserregers rechtwinklig zur Schnittlinie der zueinander geneigten Flächen steht. Gemäß einem weiteren Merkmal der Erfindung sind die beiden Flächen mit einem Belag mit hohem Reibungskoeffizient überzogen, wie z. B. Gummi mit niedriger Shore-Härte. Je nach dem zu trennenden Material kann dieser Belag auf der Materialseite mit einer profilierten Oberfläche versehen sein. Zur Sammlung der einen ausgeschiedenen Komponente dient z. B. eine mitschwingende Zusatzrinne am oberen Ende der Trennfläche. Eine Verbesserung der Trennschärfe tritt ein, wenn Querleisten in Richtung der Schwingebene auf der Trennfläche angebracht sind, besonders, wenn diese Leisten in Transportrichtung eine zunehmende Länge aufweisen.The invention avoids these disadvantages of these known devices, by the vibrating channel provided for the classification of material mixtures two surfaces inclined at a certain angle to each other, the intersection of which forms a further angle to the horizontal and the pulse direction of the vibration exciter perpendicular to the intersection of the inclined surfaces. According to a Another feature of the invention are the two surfaces with a covering with a high Coefficient of friction coated such. B. rubber with low Shore hardness. Depending on the material to be cut can be this covering on the material side with a profiled Be provided surface. Used to collect the one excreted component z. B. a resonating additional channel at the upper end of the dividing surface. An improvement the selectivity occurs when cross bars in the direction of the oscillation plane on the Separating surface are attached, especially if these strips face the direction of transport have an increasing length.
F i g. 1 zeigt eine Klassiervorrichtung im Querschnitt; F i g. 2 zeigt den Grundriß dazu; F i g. 3 zeigt einen Seitenriß.F i g. Fig. 1 shows a classifying device in cross section; F i g. 2 shows the floor plan for it; F i g. 3 shows a side elevation.
In F i g. 1 bedeutet 1 und 2 die um den Winkel 7 zueinander und um den Winkel 3 gegen die Horizontale geneigten ebenen Flächen, die eine Rinne bilden. x-x ist die Schnittlinie der beiden ebenen Flächen 1 und 2, welche mit der Horizontalen einen Winkel 4 einschließt. Zwei Schwingungserreger 5 erzeugen eine Schwingung in der Ebene z-z, welche mit der Trennfläche 2 einen Winkel 6 bildet. Die Schwingungsrichtung y-y steht dabei auf der Schnittlinie x-x senkrecht.In Fig. 1 means 1 and 2 which are at the angle 7 to each other and around the angle 3 against the horizontal inclined flat surfaces that form a channel. x-x is the line of intersection of the two flat surfaces 1 and 2, which with the horizontal includes an angle 4. Two vibration exciters 5 generate a vibration in the z-z plane, which forms an angle 6 with the separating surface 2. The direction of vibration y-y is perpendicular to the intersection line x-x.
Die Unterstützung der Rinne ist in der Zeichnung beispielhaft auf Gummifedern 14 gezeigt. Die Oberseite der Flächen 1 und 2 können mit einem Belag 8 versehen sein, der einen hohen Reibungskoeffizienten besitzt. Eine Zusatzrinne 9 dient zum Sammeln und Abführen der einen Komponente, während die andere Komponente am Rinnenende 10 abfließt. Verschieden lange Leisten 11 sind auf der Trennfläche in Richtung der Schwingungsebene so angebracht, daß deren Länge in der Transportrichtung zunimmt. Die Materialaufgabe erfolgt zweckmäßig bei 12 derart, daß der Auftreffbereich einer länglichen Fläche 13 entspricht.The support of the gutter is exemplified in the drawing Rubber springs 14 shown. The top of surfaces 1 and 2 can be covered with a covering 8, which has a high coefficient of friction. An additional channel 9 is used to collect and discharge one component, while the other component at the end of the channel 10 flows off. Bars 11 of different lengths are on the parting surface in the direction of the plane of vibration so attached that its length in the direction of transport increases. The material is expediently applied at 12 in such a way that the impact area corresponds to an elongated surface 13.
Wird eine solche Rinne in der beschriebenen Weise in Schwingungen versetzt und ein Gemisch von z. B. Strahlmittel und Quarzsand aufgegeben, wobei beispielsweise das Strahlmittel eine Körnung von 0,2 bis 1,5 mm hat, während der Quarzsand 0,05 bis 0,4 mm Körnung besitzt, so wandert der Quarzsand je nach Körnung steiler oder etwas weniger steil auf der Trennfläche nach oben und gelangt spätestens am Ende der Rinne über den höchsten Punkt der Trennfläche in die mitschwingende Rinne 9. Brauchbares Strahlmittel aus Metall z. B. ist nicht in der Lage, die Steigung der Trennfläche zu überwinden, sondern folgt zier Neigung der Trennfläche gemäß dem Winkel 4 und fließt am tiefsten Punkt der Rinne 10 ab.If such a channel vibrates in the manner described added and a mixture of z. B. Abandoned abrasives and quartz sand, with For example, the abrasive has a grain size of 0.2 to 1.5 mm, while the If quartz sand has a grain size of 0.05 to 0.4 mm, the quartz sand migrates depending on the grain size steeper or a little less steeply upwards on the interface and reaches at the latest at the end of the channel over the highest point of the separating surface into the oscillating Channel 9. Usable blasting media made of metal e.g. B. is unable to the Overcoming the slope of the interface, but follows the decorative slope of the interface according to the angle 4 and flows off at the lowest point of the channel 10.
